A Developer Demos Flying JB for iOS 9.2.1 Jailbreak

One of the well-known Chinese developers, Min Zheng aka @SparkZheng has recently refreshed jailbreak crowd by publishing Flying JB for iOS 9.2.1 jailbreak. As to what he demos, this new jailbreak concept has successfully worked on an iPhone 5c running iOS 9.2.1, but if we have a closer look this Flying JB is a different process than what you already familiar with other jailbreak techniques, Therefore we thought of sharing some of the important facts about Zheng’s Flying JB as a support for those who willing to take this new jailbreak experience.

In the end of a successful jailbreak, yo get Cydia on iOS, but as to Zheng’s Flying JB we do not hear about Cydia install on iOS 9.2.1 after the jailbreak. As I started saying this is not like Pangu jailbreak or TaiG you often hear, in fact, this installs an unsigned Mobile Terminal app with the process with Flying JB, which gives user the facility to run any command as root. But we do not hear Cydia with Flying JB.

As to Zheng Flying JB has developed on “inpuTbag”, a 15 years old kernel HeapOverFlow vulnerability which is known for years as a powerful exploit. But unfortunately the latest iOS 9.3.2 has come fixed with these security weaknesses, which means this concept is no use for recent iOS 9 versions that users are eagerly waiting to jailbreak. In that way Flying JB is only to make iOS 9.2.1 jailbreak crowd happy.

Jailbreak with Flying JB

Flying JB is not a GUI based tool like Pangu or TaiG jailbreak, therefore it will not be easy to handle like other user supportive jailbreak tools. Even though this new jailbreak technique sounds interesting, it does come with limitations, which would make Flying JB less interesting for you.

Flying JB only supports 32-bit device models, meaning it only going to be work on iPhone 5 or lower models. The other thing is, you have to be on iOS 9.2.1 or lower to work with Flying JB. In that way Zheng’s new jailbreak concept will only work for a limited crowd. But if you are looking for iOS 9.2.1 jailbreak on your iPhone 5 or lower, give it a try and make us too aware about your experience with Flying JB.

Source codes are available in Github for those who wish to proceed with Flying JB and you will also be guided with clear instructions,but remember to check the device’s compatibility prior to start iOS 9.2.1 jailbreak with Flying JB and remember it still lacks sandbox escape where you will not get a complete jailbreak.

If it still sounds great, give it a try and tell us how adventurous your time with Flying JB.
